Trials were conducted to evaluate the effects feeding rate and salinity levels on growth<br />

performance of red hybrid tilapia fingerlings. During the first trial, a total of 21 fish<br />

with individual body weight (BW) averaging 1.0±0.1 g (mean±SD) were fed a<br />

commercial diet for 2 weeks at 3%, 5% and 7% body weight at 28 o C and determined<br />

their growth performance. Based on the results of the first trial, another experiment<br />

was carried out (n=21) for another 14 days at different salinity levels i.e. 0, 7, 14 ppt.<br />

Weight gains of fish at 7% feeding rate were significantly higher (p0.05). For salinity<br />

experiment, the results showed that BWG and SGR were higher at 0 ppt which<br />

corresponding to the lowest feed convention rate. This study indicates that fingerlings<br />

of red hybrid tilapia may acquires feeding rate given at 7% body when cultured at 0<br />

ppt.<br />
